To QH fui/mm 'it may concern Be it known that. il, YilVILLImi R. Ilusion', a citizen ot the United States, residing at tladeden, in the county of ltowali :ind State of Alabama. have invented ne end useful improvements in illuminated Signe, ot. which the following is a sl'ieeitcation.

lfhie` intention` relates to illuminated signs ot that type set forth in YUnited States Ptitent filo, ltlntfi, granted to itt. McNeal, Dec. l, i308. herein the lettei'sot the sign are `toi-ined by a plurality o ligheretlecting diste; arranged in the outlines ot' the letters, the source of light being one or more linups so disposedthat the rays o" light strike the dighe ind are reflected thereby.-

'the invention has tor one oil its objects to improve sign:` of this charac-.ter sol as to obtain a better illuminating eti'ect riu'ipart e. better appearance to the Signgiat the saine ltime enablingthe letters to be inade of sheet inetail olf comparatively light gage.

Another object ot' the invention is the provision ol a sign in which the disks are iliade ot concern-conrex.terni so thatl the convex .l ight-reilecting sides give inore nearly the appearance ol bulbeor beadti oli' lightv which, teken together with the eonrixity olf the edge?. ol' thel openings from wliieli'the dieks are stamped in the pitite ot' the letter, iinproves the illuminatingf ellect. Furthermore, the convening ot the plate of the let.- ter and of the disks `greatly strengthens the letter und enables a sheet ot thin gage to be used.

With these and other objects in View, the

.invention coluprises the various novel features ol construction und arrangen'ient of parts which u'ill be more fully described hereinafter and set forth with particularity in the claims appended hereto.

ln the accompanying drawing, which illustrates one embodiment of the ini'entioii, Figure l in a l'ront View ot' a sign letter. Fig. 2 is a vertical transferee section thereof. Fig, 3 is nu enlarged detail section through one of the light reflecting disks ofthe letter. Similar reference charactersareemployed lo designate correspondiny?` parte' throughout. the views.

'The curvingr ot' the disks an(l Vtront'plate of the sign also uuueri-illy :strengthens the letter and permits ot the use ot comparatively thin metal.

The rays ol' light .troni the lamp in the hotly of the sign strike the convex sides of the disks and are reflected in a generally forward direction, the retlected rnyfs being more in the forni of pencils than beams of light due to the curvature of the reflecting surfaces. Soniejot the rays of light strike the convex edges of the front plate and are in turn rellected troni such edges so that the outline oi. each letter stands out clearl", to the vision of the observer.

While the openings and disks in the tace plate a're disposed to forni thcvarious characters constituting the sign, it will be desirable to paint the outlines of the Asinne ehitraeters en the iiont side oif the plate il with white er other suitable paint or equiv by day, `the bacligrtuuid of the Sign heling ot' any suitable color.
